Hi all,
During my SWAH build, I managed to break two 1n34 diodes when bending the legs ;(
I have D9B diodes laying around (10V, 40mA. Vf = 0,4V) I also have multiple bat41 diodes. Can these be used instead? Or by combining these in series/parallel or with resistors (I’ve looked solutions up online but it’s mostly about diodes used in distortion/fuzz circuits)
Hope anyone can help!
Put sockets in the pads, then go ahead and try whatever you have!
And remember to use plier to bend the leads, not fingers. I also cracked a 1n34 lately by nudging it around too hard.
I just finished a SWAH, myself. Didn’t try the D9B I have sitting around (remember, soviet diodes are marked backwards), but that Vf is in line with the upper end of 1n34 I’ve seen.
I ended up using a bat42, which is at the lower end of the 1n34 range. Mine read at .324V. Working pretty well. Test a couple bat41s, I’m betting those would work and ones on the lower end of the variance would overlap with 1n34 range.Allright thank you for the suggestions! Will socket and try out different diodes I have laying around.
Yeah, the best cheap parts I’ve ever bought is a stack of socket strips and a razor saw to cut them neatly.
Unless I’m 100% (and I never am) I socket every spot for diodes or transistors. Both keeps me from overheating them or putting them in backwards (a big possibility for soviet diodes), but means I get to play around with them for different characteristics.Hi Barry, I used pliers as you suggested to bend the legs, but wasn’t carefull enough. Still have a lot to learn and be more patient when building. I get hyped and rush through the project, then I make mistakes.
It feels like the holes on the pcb are too close to each other (or diode is bigger then usual). I added sockets now, I’ll see what different diodes do.
Another quick question for the angry llama, it is an amazing thing, has some subtle quack to it. It is the first overdrive where tone controls of my strat really interact with. I do find the upper ‘brightness’ of the pedal to harsh. Could I change a cap value or add one? Or maybe reuse the toggle for the original /preset high cut value?
Thank you all for helping me out, I’ve learned a ton online, but it reduces guesswork. Happy I’ve restarted these diy pedals! Made the artwork for the llama in 2021 but stopped after the circuit wasn’t working the first time. Now I used a pcb, much easier than veroboard!
